Purification of the leper, after his recovery from his disease. As leprosy, regarded as a decomposition of the vital juices, and as putrefaction in a living body, was an image of death, and like this introduced the same dissolution and destruction of life into the corporeal sphere which sin introduced into the spiritual; and as the leper for this very reason as not only excluded from the fellowship of the sanctuary, but cut off from intercourse with the covenant nation which was called to sanctification: the man, when recovered from leprosy, was first of all to be received into the fellowship of the covenant nation by a significant rite of purification, and then again to be still further inducted into living fellowship with Jehovah in His sanctuary. Hence the purification prescribed was divided into two acts, separated from one another by an interval of seven days.
